效果图如下:

一.创建一个UITabbarController,并在AppDelegate中的 didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法设置

    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

    //tabbar控制器
    ShopPageBarController *tab = [[ShopPageBarController alloc] init];
    self.window.rootViewController = tab;
    self.window.backgroundColor = WHITECOLOR;
    [self.window makeKeyAndVisible];

二.在 ShopPageBarController.m 文件中实现封装方法

    - (void)viewDidLoad{
        [super viewDidLoad];
        [self createSystemTabbar];
    }
    
    //自封装方法
    -(UINavigationController*)createNavWithViewController:(UIViewController *)viewController WithTitle:(NSString*) title image:(UIImage*)image
    {
        UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:viewController];
        viewController.tabBarItem = [[UITabBarItem alloc] initWithTitle:title image:image tag:0];
        viewController.title = title;
        return nav;
    }
    
    //创建系统tabbar
    - (void)createSystemTabbar{
        HomePagController *page = [[HomePagController alloc] init];
        CategoryController *cate = [[CategoryController alloc] init];
        UIViewController *vc = [[UIViewController alloc] init];
        UIViewController *vc1 = [[UIViewController alloc] init];
        UIViewController *vc2 = [[UIViewController alloc] init];
    
    //数组设置
        self.viewControllers = [NSArray arrayWithObjects:[self createNavWithViewController:page WithTitle:@"首页"  image:[UIImage imageNamed:@"icon-d-4"]],
                                [self createNavWithViewController:cate WithTitle:@"分类" image:[UIImage imageNamed:@"icond-3"]],
                                [self createNavWithViewController:vc WithTitle:nil image:nil],
                                [self createNavWithViewController:vc1 WithTitle:@"实时定位" image:[UIImage imageNamed:@"icon-d-1"]],
                                [self createNavWithViewController:vc2 WithTitle:@"我的" image:[UIImage imageNamed:@"icon-d-2"]],
                                nil];
    
        
        //中间突出按钮设置
        UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(0.0,0.0,65,65)];
        button.center = CGPointMake(WIDTH/2,15);
        [button setBackgroundImage:[UIImage imageNamed:@"icon-z"] forState:UIControlStateNormal];
        [button addTarget:self action:@selector(pickClick) forControlEvents:UIControlEventTouchUpInside];
        [self.tabBar addSubview:button];
    
        
    }
    
    //点击事件
    - (void)pickClick{
        
    }
